Yes, my car is also a '97 SC2. And according to the guys at my local Tuffy Muffler, there were no codes on their diagnostic. Although that didn't stop them from charging me $39.99 for it anyway.
They just repaired the flex pipe on my exhaust and gave it an oil change and sent me on my way. Needless to say, there are definitely more things wrong with it than that! My 'SERVICE ENGINE SOON' light has been on since I bought the car.
